and the thing people seem to not understand: how exactly do you _expect_ to be able to notice this change? Its something that happens after you take it for a prolonged period of time (>7days) and only has a minor/medium effect.

It doesn't make you a genius. I think a better view on it is that it may mitigate some of the adhs symptoms (at least for me).

I can keep on track for a significantly longer time since ive started supplementing with it at ~15g/day - and while i dont feel a difference, i can observe it when actually paying attention to what i do / how often i drift off etc.
